Kansas City 2, Philadelphia 1: Chuck Harrison drove in both runs for the Royals, one on a bases-loaded walk and the second on a home run.

Dave Wickersham got the win with two perfect innings of relief, and Moe Drabowsky pitched a scoreless ninth for the save. Grant Jackson went the distance for Philadelphia; he struck out seven and allowed four hits, but he also walked four and hit a batter. The Royals' Paul Schaal was injured for five games; he will be replaced on the roster by Scott Northey and is eligible to return for the games of May 1.

San Diego 2, Seattle 0 (12 innings): Dick Kelley of the Padres and Steve Barber of the Pilots each threw nine scoreless innings. Kelley faced one batter over the minimum with the aid of a caught stealing and a double play; he allowed two hits and a walk while striking out 10. Barber allowed four hits and three walks while fanning eight. Frank Reberger and Diego Segui continued the shutout pitching for two innings before the Padres broke through against Bob Locker for two runs in the top of the 12th. Billy McCool worked a hitless 12th for the save.

Montreal 2, California 1: A series of gaffes by Angels centerfielder Jay Johnstone with two outs in the ninth gave the game to the Expos. Rudy May carried a 2-1 lead into the ninth, and with two out and Ron Brand on first, Reny Hermoso hit a fly ball to center. Johnstone turned it into a Little League homer; the official scoring ruling was a double and RBI, with Hermoso scoring the winning run on a Johnstone error. May struck out seven and allowed six hits in the loss. Jim Spencer was 3-for-4 with a triple, a run scored and an RBI for the Angels. Dan McGinn was the winner with two scoreless innings of relief.
